The tench is a much overlooked pond fish, yet its feeding habits and docile temperament make them an asset to any pond ecosystem. As a rule tench are not surface feeders and can be instead found in the deep/mid-water depths of a pond, rooting around the debris at the bottom in the hope of finding larvae and aquatic insects. In effect they can act as a ‘pond cleaner’ helping to regulate algae growth and the organic matter content in a pond ecosystem. Therefore, like the gudgeon, it is advised that if you are keeping tench that some sinking fish food is used to sustain them. They can grow up to 14lbs in weight and 70cm in length in some cases but most will grow to a much smaller size, even at full maturity (around 40cm).
